Open source speaking height/speed/variometer

Hi, this is my open source airspeed / height / variometer for R/C gliders. The voice/vario sound is generated on board the plane and sent to the ground by a audio link. The speed and height are spoken with regular intervals, first the speed in km/h and then the height above ground in meters.

Talking sailplane airspeed / height / vario test (2 min 37 sec)






The reason for the huge micro-controller package is simple, I ordered the wrong one!

Source code and Eagle PCB layout is attached.

Todo:
-New smaller layout
-Controll by R/C channel.
-Increase maximum sensable height.
